Worked on the Crossmint/crossmint-sdk repository, focusing on integrating the native DeviceSignerModule into the React Native UI to streamline onboarding and enhance wallet security. Leveraged JavaScript and TypeScript to default wallet storage to NativeDeviceSignerKeyStorage, simplifying installation and improving performance. Addressed critical build issues by resolving Metro bundler resolution problems and stabilizing dependencies within the pnpm monorepo. Removed the expo-device-signer package, embedding the native bridge directly to reduce maintenance overhead. Updated the Expo demo for React Native 0.82 compatibility and aligned type interfaces, ensuring smoother downstream integration and a more robust, maintainable mobile development workflow.
